SPEGIFLCATION forming part of Letters Patent No.- 708,607, datedSeptember 9, 1902.

Application filed January 3l, 1902. Serial No. 91.986. (No model.)

To all whom, it 11m/y concern:

Be itknown that we, FRANK W. WOOD and MERCER R. MAoPHERsoN, citizens ofthe United States, residing in Chelsea, in the county of Suifolk andState of Massachusetts, have invented new and useful Improvements inHorseshoe-Pads, of which the following is a specification.

This invention relates to horseshoe-pads of the style comprising arubber cushion having one or more air-chambers and a layer of leatherVor equivalent material between the rubber cushion and the hoof ofv theanimal; and it consists in the novel construction and arrangement ofparts fully described below, and illustrated in the accompanyingdrawings, in which- Figure l is a plan view of the bottom of the rubbercushion makingra part of the pad. Fig. 2 is a top view of the same. Fig.3 is a top View of the entire pad, comprising the cushion and leatherlayer in position with relation to each other. Fig. 4. is a sectiontaken on line 4, Fig. 3, the position of the shoe being indicated bydotted line. Fig. 5 is a side View of the same. Fig. 6 is a similar viewof the pad in position on the shoe.

Similar letters of reference indicate corresponding parts. l

A represents a rubber cushion molded in a single piece. The under sideof this cushion is formed with a tread comprising the thickened heelportion B, from which extends forward an elliptical or oval portion C.The portions B and C are of the same thickness, which is somewhatgreater than that of the shoe S, which is adapted to lie next the outerportion A on the under surface of the cushion, such portion extendingfrom the heel portion B around the toe between the portion C and theedge. From the heel portion B forward, outside the portion C andconnecting with the portion A', are inclines D, and the shoe S is Therecess C', formed by the portion C of the tread, produces a suctioneffect as the horse treads, and the toe-part C of said portion C isbeveled offrearward .to render the tread a triiie more yielding at thatpoint and assist the operation of Walking.

The upper surface of the cushion Ais provided with a recess E centrallyat the heel and above the part B, and from this recess an oval orelliptical groove F extends, corresponding with the part C on the underside of the cushion. The groove F and recess E constitute an air-cushionbetween the hoof and the pad, and the recess Eis important and efficientin preventing frog-pressure.

H is alayer of leather or equivalent material corresponding in generalshape to that of the cushion and lying between the cushion and the hoof.This, layer has a hole H coincident with the recess E and a number ofholes H" registering with the groove F, whereby air enters saidgrooveand recess and is cushioned therein by direct contact with thehoof.

The relative position of the parts when the shoe is applied isillustrated in Fig. 6, the nailsbeing driven through the shoe S, cushionA, and layer H, securing the shoe and pad to the hoof. 4

Having thus fully described our invention, whatwe claim, and desire tosecure by Letters Patent, is-

In a horseshoepad,in combination,the rubber cushion comprising the mainportion A, the heel portion B, and the substantially elliptical treadportion C, said cushion being formed on its upper surface at the pointwhere the frog is liable to press, with the recess E connecting with thegroove F but having no connection with or passage leading to the edge ofthe cushion; and the leather layer H provided with the hole H' locatedat the heel' but having no connection with or passage to the edge of thelayer, and being coincident or registering with said recess, for thepurpose of preventing frog-pressure, substantially as set forth.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
